I think either 80/87 and 156 will move to compassvale
interchange cos 80 & 87 has similar routes till hougang central
and there is 159/43/43M to complement 156 along buangkok green and
yck rd..... ur views??
Not really because svc 87 is the only bus that connects blks at
Compassvale Rd towards Sengkang East Ave with Sengkang MRT while
svc 80 connects the blks at Compassvale Dr (alt: 86) and Punggol
Road (alt: 163).
If you notice, most people who board at Sengkang MRT during PM
peak will usually alight at these stops that I mentioned above on
svc 80/87.
I agree that 156 should move. 159 also. Both stop outside
Compass1, so people have option to either walk to Compassvale
Interchange or take it from Sengkang East Ave. I would also
recommend 372 but more unlikely since it is a feeder. All other
services should stay in current Sengkang Interchange.
